Here's the opinion of one of the best players from St. Petersburg - Antal:
By the way, what a terrible game chess is!
There's only one map, and it gets boring quickly.
There are only six types of units.
Everyone has the same damage.
You can only upgrade pawns.
There are no health potions. There is no respawn.
The king can only strafe.
You can't rush with pawns at the beginning of the game.
There's only one spell - checkmate.
And most importantly - there's no lava.
