WTSD – it is very important indicator which shows how often a player comes to a showdown after seeing the flop. In case this indicator is higher than 40 %, you should forget about bluffing and play only the strong hands. In case the indicator is lower than 25 %, you can try to win the pot by bluffing but if there is a strong resistance, you should fold a weak hand. For a player with a short stack 30 or 40 % WTSD is absolutely normal due to the fact that it is often advantageous to go all – in on the pre – flop or on the flop. For a player with a large stack 20 – 30 % WTSD is preferable.
