Most of the time looking at a match and deciding who is the better team is an easy choice. An important factor is often overlooked which is the Map Veto.
What is a Map Veto?
The Map Veto is the ban and pick process before the match is played. There is different formats for the Map Veto which decides the ban/pick order and amount. The most common Map Veto for a best of one is: “Team A bans, Team B bans, Team A bans, Team B bans” till there is only 1 map left which will be played for this match. For a best of three the Map Veto is usually: “Team A bans, Team B bans, Team A picks, Team B picks, Random last map out of the remaining”. This decider map is often randomized out of the remaining maps to not given a team the advantage and leave the last map to having a good map pool.
What is important about the Map Veto?
The Veto process is very important when you are aware that one of the teams that will play has a very outstanding map where they usually win. Or if the team has a very bad map that will almost always result them in losing it.
Sometimes the map information is available before the match is played which means you have all the information of the maps at your disposal. To get the best bet with this information you have to decide the chances of the teams winning on each map. Let’s say that the maps are “Mirage, Cache and Dust 2 as decider”. Team A has a 20% chacne to win Mirage, Team A has a 60% chance to win Cache and has a 90% chance to win the final map Dust 2. In this case you can say that team A will definilty take map 3 but this match is still a very dangerous match. The risk factor here is that the first 2 maps played are in the favor of Team B. If the match is 0:2 the final map will not be played. That’s why it would be better to put a bet on Team B because there is a high chance they’ll take this match 2:0.
What if you don’t know which maps are played?
When this is the case you have to do a more in depth reserach about the teams. How many maps can they play properly? Some teams refuse to play maps because they do not practise them or just don’t feel comfortable playing on these maps. This makes them a very easy team to Veto against because there isn’t as many maps to be scared of from these teams. This leaves the team without a big map pool in a huge disadvantage and will most likely result in a lose if the other team has a bigger map pool. What do they ban the most? Usually the teams either ban their worst map or their opponents best map. If this is the same map the will have a huge advantage going into the Veto because they can ban what they don’t want to play and their opponents strongest pick with a single ban.
The next step is to play out the Map Veto in your head. Let’s say it’s a: ban,ban,pick,pick,random Veto.
- Team A bans Cache
- Team B bans Cobblestone
- Team A picks Mirage
- Team B picks Overpass
We are expecting each team to win their own map pick in this scenario so lets look at what happens if the score is 1:1 and they have to play the decider map. The decider map would be: “Train, Dust 2 or Nuke”. We have to look at who has the highest chance to win on each of the possible maps as followed:
- Train: Team A 60/40 Team B
- Dust 2: Team A 50/50 Team B
- Nuke: Team A 65/35 Team B
Looking at the chances the best team to bet on would be Team A becasue they have a much greater chance of winning the decider map. Especially because they have a bigger chance of winning in 2 out of the 3 maps and the remaining map would be a 50/50 match.
If you use this system for predicting the Map Veto you have a better idea of which maps will be played and how these will be played out. The decider map is random in this case so you have to do a chance prediction for each of the available maps. This decider map comes down to a bit of luck but taking the average % chance over all 3 maps should yield you an accurate perception of who is going to win the decider.
