The Ljubljana Conspiracy.

[stigmata]

Also, he sometimes waits for the turn to raise with top/middle pair. Waiting for the turn to raise with both medium and high strength hands balances his common turn semi-bluffs. This part of his game seems designed to exploit "robotic" ABC type players who are raising preflop, and then auto-betting the flop/turn when HU, but folding often to turn check-raises.

He seems to be exploiting the fact that these ABC-TAGs are often putting too much in the pot with the worst hand postflop, but conversely is also exploiting fold equity on the turn.

This analysis is based on an extremely limited number of hands, so please be circumspect.
