#### Streszczenie

In the main result, partially answering a question of Telgársky, the following is proven: if $X$ is a first countable $R_0$-space, then player $\beta$ (i.e. the EMPTY player) has a winning strategy in the strong Choquet game on $X$ if and only if $X$ contains a nonempty $W_{\delta }$-subspace which is of the first category in itself.
